I need to make a simple one for my daughters entrepreneur day at school.
- Bubble is great for non-coders. Their native mobile app developer is still in beta but it works. There is tons of tutorials and posts about using Bubble although one downside is that there isn't too much documentation for native apps just yet. For your use case, I think it may be a good option and if you need help, check out tutorials from codelessacademy.com :)
- While Fuse Studio is awesome, as pointed out, it does require some basic JS knowledge. That's why I'd recommend Ionic Creator. Style-wise it's quite opinionated, but the fact that you can drag-and-drop a small, but key selection of elements onto a screen to build your app is pretty neat. Plus you can sync your project with the Creator App to avoid any (usually stressful) deployment process.
